Business ProfileforAdvantage Hyundai

On 7/29/2024, I entered into a purchase for a certified preowned 2021 Hyundai Elantra. The salesman contacted my insurance company and insurance was issued effective immediately while we awaited the finance agent. Due to inability to obtain the insurance binder as it was past business hours of my agent, we agreed to complete the sale on 7/30. We requested to see the carfax in advance if the finalization. On 7/30, I obtained a bank check to pay the vehicle in full and the dealer scheduled us for a 3:30pm pickup. At 2pm, the salesperson called to say the sale could not proceed due to an issue with the odometer reading. When we reviewed the carfax, this odometer discrepancy is noted. How is it possible that a dealer offers a vehicle that is not eligible for sale? I asked to speak with a manager to determine options and have not received any response. Additionally, I asked for a letter to remove the insurance that was already in place and have not received that either. The salesperson was ******************* and the sales manager is *************************. As there was no urgency to the sale, I really wanted to understand the options available not be told that I could pick another car- at a higher cost. We gave a $500 deposit via personal check.
